FLUSHING HOPPER FOR SHALLOW DEEP DBEDGERS.

Application filed January 22, 1921. Serial No. 439,275.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3,1921, 41 STAT.14,1313.)

To all whom it may concern:

Be it known that I, l/VILHELM WEBER, a citizen of the GermanRepublic,'residing at Wiesbaden, Germany, have invented certain new anduseful Improvements in Flushing Hoppers for Shallow and Deep Dredgers(for which I havefiled an application in Germany Nov. 24, 1919, PatentNo. 32%,792), of which the following is a specification. 1

This invention relates to a flushing hopper designed to receive thematerial which has been dredged (for example of brown coal openworkings) directly from the dredger, said hopper being placed upon thepassage way of the dredger. The material is admixed in the hopper withwater and then conducted to the flushing conduit.

In order that the invention may be clearly understood I shall proceed todescribe the same with reference'to the example of construction shown inthe accompanying drawing, wherein 1-- Fig. 1 shows the dredger inelevation.

Fig. 2 is an end view of the same.

Fig. 3 is a cross section on line AB of Fig. 1, and

Fig. 4 is the other end view of the same.

The device consists of a flushing hopper 1 which is about 10 meters longand mounted on wheels so that it can'run upon rails. This flushinghopper is of such dimensions that it can be introduced in the passageway of the dredger so that the dredger can move over it and empty itscontents into said hopper. The flushing conduit 2 is arranged at one endof said hopper and connected with the flushing main by means of amovable connecting sleeve. At the other end of the hopper the water pipe3 is mounted. In the hopper two gutters 4 are arranged which getnarrower in the direction in which the material is flushed and whichjoin in a pressure apparatus. Several spraying nozzles 5, 6 and 7connected with the water pipe are mounted in the side walls of saidgutters.

The operation of the device is as follows The flushing hopper is runupon the rails site the flushing conduit and means below the shootingtrap and connected with the flushing conduit which is placed along Thewaterpipe 3 is also conthe clearing. nected with the water main by meansof. a flexible tube. When the dredger begins to workthe buckets give uptheir contents into the hopper. The material which comes from thedredger isseized at 5, 6, 7 or 8 by the water coming from the sprayingnozzles and is conducted by the Water to the flushing pipe 2.

Owing to the length ofthe hopper and to 'its special construction thedredger'can continue to work until the workings have been worked for theentire length of the hopper whereupon the hopper is advanced andconnected with another pipe connection of the flushing main according tothe work of the dredge The invention will be useful where materialdredged out by means of deep dredgers has to be flushed at anyconvenient place. l Vithout the device described a movable connectionbetween dredger and flushing con-' duit will be diflicult to establishso that a continuous working would be impossible or at least verydiflicult.

I claim An improved flushing hopper for material to be flushed inconnection with deep dredgers comprising in combinationwith the hopperproper, flushing gutterswhich get nar- I rower in the direction ofmovement of the material to beflushed, spraying nozzles in said guttersfor supplying the flushing water, a flushing conduit in which saidgutters terminate, means for connecting said flushlng conduit with thefixed flushing main,

a water pipe at the end of the hopper oppofor connecting said water pipewith the water main.

In testimony whereof I affix my signature in presence of two witnesses.

WILHEL WEBER.
